Target markers not visible by other party members

Tonight while fighting ADS in the binding coil of bahamut (Turn 2), we had intermittent trouble using the target marking system. The first time we had problems, our scholar was marking targets, but our black mage was unable to see the marked targets (I was able to see the marked targets without issue). We remarked targets and it seemed to work out fine. The second time the problem occurred, nobody's target markers could be seen by other party members. Besides these 2 occasions, we did not have any problems with the target marking system. We attempted the boss more than two times, but we only encountered problems with the target marking system twice during the entire run.
